Well, it is dependent on some unknown factor. When I use the app from Chrome on Ubuntu or Windows, I don't see any of the flickr, g+, or mikereyfman images (and perhaps others). When I use it on my Chromebook, I can see at least some of the flickr and g+ images, and exactly one mikereyfman image. From your screencap, it seems you can see a different subset (possibly the whole set) of the images. ﻿
